Hickman said authorities believe Leaf may have broken into other homes over the past 1 1/2 years in search of prescription drugs and is asking those victims to come forward.

Leaf has not returned calls or text messages seeking comment and a message left at his parents' phone number was not returned. He released a statement through his publicist after his first arrest on Friday that says he has "made some mistakes and have no excuses" but that he is "confident that there will be further understanding when the facts are revealed."

Leaf, a former standout quarterback for Washington State, was the No. 2 pick in the 1998 draft behind Peyton Manning. But Leaf flamed out as quarterback for the San Diego Chargers, gaining a reputation as one of the biggest busts in NFL history

Last year, Leaf had surgery to remove a benign tumor from his brain stem and later underwent additional radiation treatments.

On March 21, Leaf told an Associated Press reporter in an email exchange that he had struggled through treatments and had an MRI scheduled for the end of the month, but "I'm doing/feeling much better and am excited for the rest of 2012."
